STORAGE-BATTERY PLATE.

Specification of Letters Patent.

Application filed August 15,1906. Serial No. 330,639-

To aZZ whmn it may concern:

Be it known that I, JOSEPH BIJUR, a citizen of the United States, and a resident of the boroughof Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Storage- Battery Plates, of which the following is a specification, accompanied by drawings.

This invention relates particularly to Plant storage batteries, in which the active material is formed out of and upon lead portions of the electrodes by chemical or electrochemical action. The many advantages'. of thePlant type of plate are well recognized in this art; and the object of the present invention is to devise such a batterylate that shall be cheap to manufacture and that by reason of its design avoids undue pressure of the oxid upon the frame and of the frame upomthe OXld and the consequent straining or deformation of the parts. EX- pansion of the individual elements of the plate is permitted substantially in all directions.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of a storage-battery plate for car ng out the above objects embodying the eatures of construction, combinations of elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification andshown in the accom panyin'g win s, in which- Figure i us a side elevat on, partly broken away, of a late embodying the invention.

' Fig. 2 is a iorizontal sectional view of the same on the line a b of Fig. 1. Fig. 3 is a side elevation in perspective of one of the outside frames of the plate, viewed from the inside. Fig. 4 is a perspective view of one of the grills. Fig. 5 is a vertical sectional View of the grill on the line a d of Fig. 4. Fig. 6 is a side elevation of a form of the plate having nooutside covering, and Fig. 7 is a side elevation in perspective of one of the frames for the plate shown in Fig. 6, viewed from the inside. Fig. 8 is a detail faceview of a modification. Fig. 9 is a sectional view online 9 9 of Fig. 8. Fi 10 is a detail View of a modified form of gri l, and Fig. 11 is a side view of the grill.

According to this invention the plate is made up of a pluralityof independent elements or units supported in suitableframes in such manner as to ermit the necessary expansion and contraction in the plate without distorting the same. The plate may or may not have an outside covering, as desired.

In the drawings, A represents a suitable supporting-framework for the plate, the body of which in this instance is perforated, as shown, which forms a covering for the grills. Within the sides B and the ends 0 of the framework are provided the reinforcing transverse ribs D and longitudinal ribs E. The perforated body of the frame and the sides, ends, and ribsmay all be made integral, if desired. Suitable lugs F and G are provided connected to the frame for supporting the'same.

The grills H are adapted to be centrally supported at the intersections of the trans verse and longitudinal ribs D and E, and another perforated frame A, substantially like the frame A without the lugs, is then placed outside of the grills and suitably secured to the frame A, as by means of the screws or rivets K or by lead-burning. The perforated frame A is also provided with transverse ribs D and longitudinal ribs E, the intersections of which fall opposite the intersections of the ribs D and E of the frame A.

Suitable means are provided for cent-rally supporting the grills, and in this instance the intersections of the ribs on the frames are provided with apertures I, into which lugs or projections or trunnions J on the grills H project. In the plates illustrated four grills are shown supported upon the framework to constitute the plate, and the dimensions of the grills and the frames are such that the grills do not touch each other nor the framework at any points eXce at at the pivotal points of the grills, there y permitting free expansion in all directions. In this instance the .grills are provided with grooves or recesses L, into which the ribs on the frames project, and thereby center the grills and old them in proper relation one to the other. Any suitable means may be provided for so centering the grills.

The grills H may be constructed in any suitable manner, and'in this instance they comprise constructions suitable for formation, consisting of parallel strips 0, connected to diagonal or cross supports P, thereby dividing the plate into segments or quarters of pyramidal form. Between the rips C) are intervals, as shown. Anyothersuitable construction of grill may be provided, and variations of the eonstructionshown may be devisedin which thegrill is divided in different geometrical arrangements. The construction described, however, has been found to operate satisfactorily and well. When the grills are arran ed in the frames, their general appearance is ike that indicated :0 in Fig. 6, from which it willr-besseen thatithe sides and ends of the grills do not touch-the framework, nor do they touch each other- 1st .any points. It is to be understoodthat thegrills are arranged in Fig. 1 like Fig.- 6. From an inspection of Figs Z-itwill be seen-that the faces of thergrills do not touch the frames except at the pivotal points. :In Figs. 6 and 7 a construction like Fig. 1 is shown,v with the exception that the frames A and A are not provided with perforated body ortions, but-,consrstof the sidesand ends and C and the ribs 1) and E. One of the frames, as A is provided with thelugs F, and G. The grills aresupported astdescribed,-in apertures I at the intersections of the ribs.

In Figs. 8, 9, lO,-and.111 a modification of the plate is shown in which the grill is.pro vided with. a central web 20, forming asup- ,porting and conducting body or member for the ribs 21. The grill is provide l withlugs 22, which are'thrust through the holes 23-1n the-frame; and these lugs are burned or. riv-' eted or otherwise secured to 'the frame. The central rib is extended on all sides, so that the edges 24 project beyond the cross-ribs of the frame to keep the edges from curling over out of the plane of the plate or warping. 40 The ribs21 do not extend to the frame; but spaces 25 are left opposite their ends to allow for. expansion, while spaces 26 are left opposite their sides to allow for ex ansion.

Obviously some features 0 this invention may be usedwithout others and the invention may be embodied in widely-varying forms.

Therefore, without limiting the invention to the devices shown and described and without enumerating e uivalents, I claim, and

desire to obtain by letters Patent, the fol-- unit elements centrally supported between' the: frames at the intersectionsofsaid transverse and longitudinal ribs without touching adjacent unit elements and without touching -.the frames except at the' snpportian -points when first arran ed in position, an means for centeringisai elements.
